Eyebrows refer to the hair above the eyes on a person's face. Eyebrows have a protective effect on eyes. Eyebrows have a certain growth cycle and will naturally fall off. Eyebrows are also an important part of human facial beauty.

The main function of eyebrows is to prevent water from flowing into the eyes. The arc of the eyebrows and the direction in which the eyebrows point can ensure that water droplets flow along the sides of the face and nose without flowing into the eyes. In 2 1 century, the eyebrow arch, which was slightly prominent in human beings, still played an important role in this function.

Knowledge expansion:

Eyebrows are closely related to hair follicles and nipples. Each normal hair follicle has its own number of blood vessels extending into the hair bulb, which communicate with the branches around the lower part of the hair follicle.

It forms a capillary network towards the nipple, and the capillary network under the nipple on both sides of the hair follicle and the capillary network in the connective tissue layer of the hair follicle form a rich vascular plexus, through which blood provides nutrients needed for hair growth.

The growth of hair depends not only on the blood circulation around the hair follicle to supply nutrition, but also on the control and regulation of nerves and endocrine. Endocrine has obvious influence on hair, and androgen can promote hair follicle sheath to some extent. Endocrine includes pituitary gland, gonad, thyroid gland and adrenal gland. Therefore, mental stress and physiological reasons can also lead to eyebrow removal and eyebrow loss.

The growth period of eyebrows is about 2 months, and the dormancy period can be as long as 3-9 months, and then they naturally fall off. The speed of hair growth is influenced by gender, age, place and season. For example, hair grows about 0.3-0.4 mm every day, armpit hair is 0.2-0.38 mm, and eyebrows are about 0.2 mm. Hair grows most vigorously at the age of 15-30, and grows slightly faster in summer than in winter.
